SAME BAND COMBINER, 900 TYPE 1 PASSIVE

The Kaelus ACM0008 is a passive combiner used to combine two 900MHz base stations to a single feeder with minimal downlink (TX) Insertion loss. Normally used in conjunction with the Kaelus 900MHz TMA this combiner saves the operator capital and operational expenditure by minimising the number of feeders required.

주요특징

  • Combines two 900MHz base stations onto a single feeder with low downlink insertion losses
  • Allows the re-use of the existing antenna, 900 TMA's and feeder hardware
  • Suitable for indoor or outdoor use, suited for masthead sites with TMA/MHAs
  • Variable DC/AISG paths configured in the factory for antenna & TMA control
  • RX div ports protected against damage from erroneous Tx connection
